How to Test 🧪

1. Steps to Reproduce:
   - Step 1: Run npm run dev in nsc-events-nextjs
   - Step 2: Toggle between light/dark mode using theme switcher
   - Step 3: Navigate to Create Event, Event Detail pages
   - Step 4: Trigger snackbar notifications (attend/archive/delete actions)
2. Expected Behavior: All UI elements adapt colors based on current theme mode so should be the same, except the code change.
3. Actual Behavior: Previously, hardcoded colors remained static regardless of theme
